SEAT FOR TRACTORS AND THE LIKE.

Application filed February 2, 1921.

To all whom it may concern:

Be it known that I, WALKER De H. Lnn, a citizen of the United States,residing at East Cleveland, in the county of Cuyahoga and State of Ohio,have invented a certain new and useful Improvement in Seats for Tractorsand the like, of which the follow ing is a full, clear, and exactdescription, reference being had to the accompanying drawings.

This invention relates to an improved seat for tractors, farm implementsand the like, and it has for its objects to provide durable seat ofsubstantial construction that is very comfortable to the rider, the samebeing spring-suspended in such manner as to effectually absorb the roadshocks and vibrations, taking the thrusts in all directions, and preventtheir transmission to the driver, the parts incorporated in thestructure being of such nature as to be unaffected by exposure to theweather.

To these ends my invention may be de fined as consisting of thecombination and arrangement of elements set forth in the claims annexedhereto and illustrated in the drawing accompanying and forming a parthereof and wherein Fig. 1 is a side elevation of the improved seat; Fig.2 is a front elevation thereof; Fig. 3 is a top plan View of the springstructure with the seat removed; and Fig. 4 a bottom plan View.

The seat proper, which is designated 1, is of the pressed metal variety,and follows the standard design commonly used on farm implements and toa considerable extent on tractors, and the underneath side of the seatis provided with downward projections constituting positioning lugs 2.These lugs are arranged to engage the sides of a seat-supporting orcarrying plate 3 that is suspended from a base plate 4 by a pair oftransversely disposed scroll elliptic springs 5, and a half scrollelliptic spring 6 arranged at right angles to the former springs. Thebase plate 4 is designed for attachment to the usual seat sup port orpost'lO, and has downward projections or lugs 11 which engage over theside edges of the horizontal seat attaching portion of the post, theparts being securely connected together by bolts 12. Each of the springs5 is composed of an upper and a lower semi-elliptic section, the scrollends of the former being connected through Serial No. 441,793.

shackles 5 with the ends of the latter sections. The outer ends of thesections of spring 6 are similarly connected through the shackle 6. Itwill be seen from an inspection of Figs. 1 and 2 that the lower sectionsof springs 5 are fitted into shallow transverse grooves or channels inthe base 41. This insures the springs being securely held in positionwhen each is connected to the base by means of a single rivet 15. Thelower section of the half elliptic spring 6 occupies a groove or channelin the rear end of the base, as indicated in Fig. 1, and it extendsbeneath the lower section of the adjacent or rear transverse spring 5 sothat the same rivet 15 is utilized for connecting both of the springs tothe base. The bottoms of the rivets 5 are flush with the correspondingsurface of the base so as not to interfere with the attachment of thelatter to post 10. The upper sections of the springs 5 and 6 areconnected to the seatsupporting plate 3 by rivets 16.

Attention is called to the fact that the positioning lugs 2 of the seatdefine the corners of a square, the side dimensions of which correspondsubstantially to the width of the seat supporting plate; and the hole inthe seat through which the bolt 18 passes for connecting the seat to theplate is disposed at the center of the square. The hole in the seat,supporting plate 3 through which the bolt 18 passes is designated 19, inFig. 3. By reason of the arrangement of the positioning lugs 2, the seatmay be adjusted on the plate 3 at angles 0f 90 apart.

From this disclosure it will be seen that my invention provides a springstructure for use with a standard type of seat and seat support. Theseat and support have parts which in ordinary use cooperate to properlyposition the seat with respect to the support. These parts are in thepresent instance the downward projections or lugs 2 of the seat, and theside edges of the seat supporting portion of the post 10 wherewith saidlugs engage. Now, it will be noted that my spring structure has parts orlugs 11 corresponding to the lugs 2 of the seat for cooperation with theside edges of the seat support 10, while the side edges of the seatsupporting plate 3 constitute parts wherewith the lugs 2 of the seatengage.

In other words, the device is designed to cooperate with the post orsupport in the same manner asdoes the seat cooperate with such part;while the seat carrying plate co-acts with the seat in the same manneras the support or post ordinarily co-acts therewith. In this way ownersof standard equipment are enabled to apply thereto without any changewhatever, the device of my invention.

Having thus described my invention, what I claim is:

1. In a seat structure of the character set forth,'the combination of aseat, a seat supporting plate, a base plate for. attachment to a seatsupport, a pair of transversely disposed scroll elliptic springsinterposed between and coni'iecting said plates, and a haltscrollelliptic spring disposed at right angles to the former springs andhaving its inner ends connecting to the plates.

2. In a seat structure of the character set forth, the combination of aseat, a seat supporting plate, a base plate for attachment to a seatsupport and having transversely disposed grooves, spring leaves disposedwithin said grooves, means conectingsaid leaves to the base plate,spring leaves connected to the seat supporting plate and arrangedthereon to correspond with the arrangement ofthe former leaves on thebase plate, and shackles connecti-ngthe ends of the first and secondmentioned spring leaves.

3. In a seat structure of the character set forth, thecombin'ation of aseat, a seat supporting plate, a base plate for attachment to a seatpost or the like and having transversely disposed grooves and a grooveopening through one end of the plate and communicating with one of thetransverse grooves and being of a greater depth than said transversegroove, elliptic sprin s having their lower sections disposed wit in thetransverse grooves of the base plate and connected to said plate andtheir upper sections attached to the seat supporting plate, and ahalf-elliptic spring having the inner end of its upper section connectedto the seat supporting plate audthe corresponding end oi? its lowersection disposed within the deeper groove of the base plate andunderlying the lower section of the adjacent elliptic spring, and commonmeans for attaching the overlapping spring leaves and base platetogether.

4:. In combination with a seat support having a seatattaching portion ofa given width, and a standard seat having downward projections which arespaced apart a distance substantially equal to the width of the seatattaching portion of the support, a base plate designed for attachmentto the seat support and having downward projections that are spacedapart a distance suliistantially equal to the width of the seatattaching portion of the support, a seat carrying plate of substantiallythe same width as the seat attaching portion of the support, and springsinterposed between said plates.

In testimony whereof, I hereunto afiix my signature.
